What's Included
- U.S. Revolver Co. Automatic Hammer .32 S&W top-break revolver
Manufactured by Iver Johnson’s Arms & Cycle Works for the U.S. Revolver Co. label, this piece reflects the brand’s early 20th-century production aimed at the American market. The era of manufacture is the 1910s–1930s, aligning with the Automatic Hammer series run.
The design is a double-action/single-action top-break with automatic ejection, built on a small steel frame with a 3-inch steel barrel and an exposed hammer. Capacity is five rounds of .32 S&W.
Sighting is fixed, with a half-moon blade front and a rear notch integral to the top latch. The latch is the single-latch style with a knurled thumb piece for operation.
It retains checkered hard-rubber grips on a round-butt frame. The "US" grip medallions denote the U.S. Revolver Co. brand, not U.S. government issue.
